environment shapes our behavior and taking internal mental states such
as thoughts, feelings and emotions is useless in explaining behavior.

Behavioral theories

There are two major types of behavioral
theories:

Classical conditioning uses reflexive behavior - behavior that occurs
as an automatic response to some stimulus.

Operant conditioning is a method of learning that occurs through rewards
and punishments for behavior.

Ivan Pavlov

Behaviorism had it's earliest start with
the work of a Russian physiologist named as Ivan Pavlov. First he did research on the digestive systems
of dogs led to his discovery of the classical conditioning process, which demonstrated that behaviors could be learned
through conditioned associations.

Classical conditioning

In order to understand how classical conditioning works, it is important
to be familiar with the basic principles of the process.

Principles of Classical Conditioning

There are five principles of classical
conditioning.

1.Acquisition

2. Extinction

3.Spontaneous Recovery

4.Stimulus Generalization

5.Discrimination

1. Acquisition

Acquisition is the initial stage of
learning when a response is first established and gradually strengthened.

For example, imagine that you are
conditioning a dog to salivate in response to the sound of a bell. Once the
response has been acquired, you can gradually reinforce the salivation response
to make sure the behavior is well learned.

2. Extinction

Extinction is when the occurrences of a conditioned
response decrease or disappear. In
classical conditioning, this happens when a conditioned stimulus is no longer
paired with an unconditioned stimulus.

3. Spontaneous Recovery

Spontaneous Recovery is the reappearance of the conditioned
response after a rest period or period of lessened response. If the conditioned stimulus and
unconditioned stimulus are no longer associated, extinction will occur very
rapidly after a spontaneous recovery.

4. Stimulus Generalization

Stimulus Generalization is the tendency for
the conditioned stimulus to evoke similar responses after the response has been
conditioned. For example, if a child has been conditioned to fear a
stuffed white rabbit, the child will exhibit fear of objects similar to the
conditioned stimulus.

5.Discrimination

Discrimination is the ability to differentiate between a
conditioned stimulus and other stimuli that have not been paired with an
unconditioned stimulus. For example, if a bell tone were the conditioned
stimulus, discrimination would involve being able to tell the difference
between the bell tone and other similar sounds.

Classical Conditioning in the Real World

In reality, people do not respond exactly like Pavlov's dogs. There are,
however, numerous real-world applications for classical conditioning. For example, many dog trainers use classical
conditioning techniques to help people train their pets

Application in classroom

These techniques are also useful in the treatment of phobias or anxiety
problems.

Teachers are able to apply classical conditioning in the class by creating
a positive classroom environment to help students overcome anxiety or fear.

Skinner box

A box often used in operant conditioning of animals; it limits the
available responses and thus increases the likelihood that the desired response
will occur.

Experiment of B.F. Skinner

Place a rat in a special cage (called a “Skinner box”) that has a bar or
pedal on one wall that, when pressed, causes a little mechanism to release a
food pellet into the cage.

The rat is moving around the cage when it accidentally presses the bar
and, as a result of pressing the bar, a food pellet falls into the cage.

 The operant is the behavior just
prior to the reinforce, which is the food pellet. In a relatively short
period of time the rat "learns" to press the bar whenever it wants
food.

Principles of operant conditioning

This leads to one of the principles of operant conditioning.

A behavior followed by a reinforcing stimulus results in an increased
probability of that behavior occurring in the future.

If the rat presses the bar and continually does not get food, the
behavior becomes extinguished.

 This leads to another of the
principles of operant conditioning

if you turn the pellet machine back on, so that pressing the bar again
provides the rat with pellets, the behavior of bar-pushing will come
right back into existence, much more quickly than it took for the rat to learn
the behavior the first time.

Principles of Reinforcement

1) Positive reinforcement

Give an organism a pleasant stimulus when
the operant response is made. For example, a rat presses the lever (operant
response) and it receives a treat (positive reinforcement)

2)Negative
reinforcement take away an unpleasant stimulus when the operant response is made. For example, stop shocking a rat when it
presses the lever.

Two types of punishment

1) Positive: presentation of an aversive stimulus to
decrease the probability of an operant response occurring again. For example, a child reaches for a cookie
before dinner, and you slap his hand.

2) Negative : the removal of a pleasant stimulus to
decrease the probability of an operant response occurring again. For example, each time a child says a curse
word, you remove one dollar from his piggy bank.

Difference
between both theories

Classical and operant conditioning are two important concepts central to
behavioral psychology.

While both result in learning, the processes are quite different.

classical conditioning is passive on the part of the learner, while
operant conditioning requires the learner to actively participate and perform
some type of action in order to be rewarded or punished

Application of both theories in real world

Today, both classical and operant
conditioning are utilized for a variety of purposes by teachers, parents,
psychologists, animal trainers and many others. In animal training, a trainer
might utilize classical conditioning by repeatedly pairing the sound of a bell with the taste of food. Eventually, the
sound of the bell alone will begin to produce the same response that the taste
of food would.

Application in classroom

In a classroom setting, a teacher might
utilize operant conditioning by offering chocolate as rewards for good
behavior. Students can then turn in these chocolate to receive some type of
reward such as treat or extra play time.

Criticisms of Behaviorism

Many critics argue that behaviorism is a one-dimensional approach to
understanding human behavior and that behavioral theories do not account for
free will and internal influences such as moods, thoughts and feelings.

Behaviorism does not account for other types of learning, especially
learning that occurs without the use of reinforcement and punishment.

People and animals are able to adapt their behavior when new information
is introduced, even if a previous behavior pattern has been established through
reinforcement.

Strengths of Behaviorism

Behaviorism is based upon observable behaviors, so it is easier to
quantify and collect data and information when conducting research.

Effective therapeutic techniques such as intensive behavioral
intervention, behavior analysis, token economies and discrete trial training are
all rooted in behaviorism. These approaches are often very useful in changing
harmful behaviors in both children and adults.

Conclusion

Behaviorism is not as dominant today as it
was during the middle of the 20th century; it still remains
an influential force in psychology. Outside of psychology, animal trainers, parents,
teachers and many others make use of basic behavioral principles to help teach
new behaviors and discourage unwanted ones.
